Key Requirements for Automotive Interior Fibers
Automotive interior fibers operate in a harsh environment—exposed to high temperatures, frequent friction, sunlight, and even chemical cleaning agents. Unlike ordinary textile fibers, they must meet strict performance standards to ensure safety, comfort, and longevity. Here are the four core requirements for high-quality automotive interior fibers:
-
Low Shrinkage: Car interiors are often exposed to high temperatures (such as direct sunlight or engine heat), so fibers must have low dry heat shrinkage (<7%) to avoid deformation, wrinkling, or loosening of interior parts over time. This ensures the interior maintains its shape and appearance for years.
-
High Strength & Wear Resistance: Interior components like seats, door panels, and carpets are subject to frequent friction and pressure. Fibers with high breaking strength (≥5.4 cN/dtex) and excellent wear resistance can withstand long-term use without pilling, tearing, or fading.
-
Flame Retardancy: Safety is non-negotiable in the automotive industry. Automotive interior fibers must meet strict flame retardant standards (such as GB 8410, UL94, and BS5852) with a limiting oxygen index (LOI) ≥28. They must be self-extinguishing when away from fire, produce low smoke, and be non-toxic to protect passengers in case of an accident.
-
Environmental & Comfortable: With the rise of green mobility, fibers must be eco-friendly (low VOC, no harmful substances) and comfortable to the touch. They should also have good sound insulation and heat insulation properties to enhance the driving experience.
BZY Fiber’s Automotive Interior Fiber Solutions
At BZY Fiber, we specialize in developing and producing automotive-grade polyester staple fibers that meet and exceed industry standards. Our product lineup is tailored to different automotive interior applications, providing one-stop solutions for our customers. Here are our core products for automotive interiors:
1. Low Shrinkage Polyester Staple Fiber
Our low shrinkage polyester staple fiber is designed for automotive seats, door panels, and顶棚 (ceiling). With a dry heat shrinkage rate of <7% and high dimensional stability, it prevents interior deformation even under high-temperature conditions. Available in finenesses of 1.5D–15D and lengths of 38mm–76mm, it can be customized to match different fabric textures and hardness requirements. This fiber is also highly compatible with spinning and non-woven processes, ensuring smooth production for automotive parts suppliers.

2. Flame Retardant Polyester Staple Fiber
Our flame retardant polyester staple fiber is a core product for automotive safety. Adopting intrinsic flame retardant technology (not post-finishing), it achieves permanent flame retardancy with LOI ≥28–32, meeting global safety standards. It is non-toxic, low-smoke, and non-dripping when burned, effectively reducing the risk of fire spread. This fiber is widely used in automotive carpets, seat cushions, and sound-insulating materials, providing reliable safety protection for passengers. We offer it in white, black, and custom colors, with finenesses ranging from 1.5D to 15D.

3. Low Melt Polyester Fiber
For automotive non-woven interior parts (such as seat liners, sound-insulating cotton, and trunk liners), our low melt polyester fiber is the ideal choice. With a melting point of 110℃–150℃, it acts as a “thermal adhesive” when mixed with ordinary fibers (5%–30% mixing ratio), eliminating the need for harmful glues or resins. This makes the final product eco-friendly, high-strength, and washable. Our low melt fiber is available in 4D×51mm and 6D×64mm specifications, suitable for hot-air bonding and needle-punching processes.

4. Hollow Sound-Insulating Polyester Fiber
To enhance driving comfort, our hollow sound-insulating polyester fiber is designed for automotive ceiling, door panels, and floor mats. With a hollow structure and three-dimensional crimp, it has excellent sound insulation and heat insulation properties, reducing road noise and maintaining a comfortable temperature inside the car. It is lightweight, fluffy, and resilient, ensuring long-term comfort without collapsing. Available in 3D–15D fineness and 64mm–76mm length, it is the perfect material for premium automotive interiors.
